RP1–06/07 P2603.2.1, M1308.2; IPC 305.8; IFGC 404.5; IMC 305.5 Proponent: Randall Shackelford, Simpson Strong-Tie Co. THIS PROPOSAL IS ON THE AGENDA OF THE IRC-P, IPC, IFGC AND THE IMC CODE DEVELOPMENT COMMITTEES. SEE THE TENTATIVE HEARING ORDERS FOR THESE COMMITTEES. PART I – IRC PLUMBING Revise as follows: P2603.2.1 Protection against physical damage. In concealed locations, where piping, other than cast-iron or galvanized steel, is installed through holes or notches in studs, joists, rafters or similar members less than 1.5 inches (38 mm) from the nearest edge of the member, the pipe shall be protected by shield plates. Protective shield plates shall be a minimum of 0.062 0.054-inch-thick (1.6 1.37 mm) steel, shall cover the area of the pipe where the member is notched or bored and shall extend a minimum of 2 inches (51 mm) above sole plates and below top plates. M1308.2 Protection against physical damage. In concealed locations where piping, other than cast-iron or galvanized steel, is installed through holes or notches in studs, joists, rafters or similar members less than 1.5 inches (38 mm) from the nearest edge of the member, the pipe shall be protected by shield plates. Protective shield plates shall be a minimum of 0.062 0.054-inch-thick (1.6 1.37 mm) steel, shall cover the area of the pipe where the member is notched or bored, and shall extend a minimum of 2 inches (51 mm) above sole plates and below top plates. PART II – IPC Revise as follows: 305.8 Protection against physical damage. In concealed locations where piping, other than cast-iron or galvanized steel, is installed through holes or notches in studs, joists, rafters or similar members less than 1.5 inches (38 mm) from the nearest edge of the member, the pipe shall be protected by shield plates. Protective shield plates shall be a minimum of 0.062 0.054-inch-thick (1.6 1.37 mm) steel, shall cover the area of the pipe where the member is notched or bored, and shall extend a minimum of 2 inches (51 mm) above sole plates and below top plates. PART III – IFGC Revise as follows: 404.5 Protection against physical damage. In concealed locations, where piping other than black or galvanized steel is installed through holes or notches in wood studs, joists, rafters or similar members less than 1.5 inches (38 mm) from the nearest edge of the member, the pipe shall be protected by shield plates. Shield plates shall be a minimum of 1/16 0.54-inch-thick (1.6 1.37 mm) steel, shall cover the area of the pipe where the member is notched or bored and shall extend a minimum of 4 inches (102 mm) above sole plates, below top plates and to each side of a stud, joist or rafter. PART IV – IMC Revise as follows: 305.5 Protection against physical damage. In concealed locations where piping, other than cast-iron or steel, is installed through holes or notches in studs, joists, rafters or similar members less than 1.5 inches (38 mm) from the nearest edge of the member, the pipe shall be protected by shield plates. Protective shield plates shall be a minimum of 0.062 0.54-inch-thick (1.6 1.37 mm) steel, shall cover the area of the pipe where the member is notched or bored, and shall extend a minimum of 2 inches (51 mm) above sole plates and below top plates. Reason: Revise outdated material This section of the Code seems to be based on a nominal 1/16” steel thickness which approximates a 16 gauge steel thickness. Fractional and gauge thickness references are an obsolete method of specifying sheet steel. The current unit for designating steel thickness is in decimals of an inch or mils. The current provision of a minimum of 0.062-inch-thick steel (62 mils) is generally unavailable from steel mills. To meet current code provisions, shield plates would have to be manufactured out of 0.068-inch (14 gauge) steel. 14 gauge steel shield plates is not the intent of the current code provisions. There is also a conflict with provisions within Chapter 6. Section R602.6.1 requires a “tie of not less than 0.054 inch thick (16 ga)” when the top plate is cut or notched for piping. This change will allow the same product to be used to meet both sections, thereby saving materials and money. Table A5.1-1 of the 2001 Standard for Cold Formed Steel Framing provides current designations in mils for “old reference gauge number”. 16 gauge is currently designated as 54 mils in this table. Table R603.2(2) also lists the minimum uncoated thickness of 0.054 inches as equivalent to 16 reference gage.

RP2–06/07 P2705.1 Proponent: Guy Tomberlin, Fairfax County, Virginia, representing Virginia Plumbing and Mechanical Inspectors Association (VPMIA) and the Virginia Building Code Officials Association (VBCOA) Revise as follows: P2705.1General. The installation of fixtures shall conform to the following: 1. Floor-outlet or floor-mounted fixtures shall be secured to the drainage connection and to the floor, where so designed, by screws, bolts, washers, nuts and similar fasteners of copper, brass or other corrosion-resistant material. 2. Wall-hung fixtures shall be rigidly supported so that strain is not transmitted to the plumbing system. 3. Where fixtures come in contact with walls and floors, the contact area shall be water tight. 4. Plumbing fixtures shall be usable. 5. The centerline of water closets or bidets shall not be less than 15 inches (381 mm) from adjacent walls or partitions or not less than 15 inches (381 mm)from the centerline of a bidet to the outermost rim of an adjacent water closet. There shall be at least 21 inches (533 mm) clearance in front of the water closet, bidet or lavatory to any wall, fixture or door. 5. Water closets, urinals, lavatories and bidets. A water closet, urinal, lavatory or bidet shall not be set closer than 15 inches (381 mm) from its center to any side wall, partition, vanity or other obstruction, or closer than 30 inches (762 mm) center-to-center between adjacent fixtures. There shall be at least a 21-inch (533 mm)clearance in front of the water closet, urinal, lavatory or bidet to any wall, fixture or door. Water closet compartments shall be not less than 30 inches (762 mm) wide and 60 inches (1524 mm) deep. 6. The location of piping, fixtures or equipment shall not interfere with the operation of windows or doors. 7. In areas prone to flooding as established by Table R301.2(1), plumbing fixtures shall be located or installed in accordance with Section R323.1.5. 8. Integral fixture-fitting mounting surfaces on manufactured plumbing fixtures or plumbing fixtures constructed on site, shall meet the design requirements of ASME A112.19.2 or ASME A112.19.3. Reason: This is the text that was approved in the IPC last code cycle. It provides clear, appropriate information and guidance that needs to provided in the IRC. Cost Impact: The code change proposal will not increase the cost of construction.

RP3–06/07 P2706.2.1

Proponent: Guy Tomberlin, Fairfax County, Virginia, representing Virginia Plumbing and Mechanical Inspectors Association (VPMIA) and the Virginia Building Code Officials Association (VBCOA) Revise as follows: P2706.2.1 Laundry tray tub connection. A laundry tray tub waste line is permitted to connect into a standpipe for the automatic clothes washer drain. The standpipes shall not be extend not less than 30 inches (762 mm) as measured from above the crown trap weir. and shall extend above the flood level rim of the laundry tub The outlet of the laundry tray shall be a maximum horizontal distance of 30 inches (762 mm) from the standpipe trap. Reason: The laundry tub is a reservoir that can attempt to handle a large quantity of water in a short period of time. It also can hold a large amount of water. If the standpipe terminates below the flood level rim of the laundry tub and the laundry tub is full, the discharge from the laundry tub itself could overflow the standpipe. The text is also revised to imitate the standpipe height measurement found in Section P2706.2. Cost Impact: The code change proposal will not increase the cost of construction.

Proponent: Charles E. Gerber, County of Henrico, Virginia, representing Virginia Plumbing and Mechanical Inspectors Association (VPMIA) and the Virginia Building Code Officials Association (VBCOA) Revise as follows: P2706.3 Prohibited waste receptors. Plumbing fixtures that are used for domestic or culinary washing or bathing purposes shall not be used to receive the discharge of indirect waste piping. Exceptions: 1. A kitchen sink trap is acceptable for use as a receptor for a dishwasher. 2. A laundry tray is acceptable for use as a receptor for a clothes washing machine. Reason: The existing terms are typically associated with commercial applications. The terms washing and bathing are more appropriate for residential installations. Cost Impact: The code change proposal will not increase the cost of construction.

RP5–06/07 P2717.1

Proponent: Cecil F. Hardee, Jr., County of Fairfax, Virginia, representing Virginia Plumbing and Mechanical Inspectors Association (VPMIA) and the Virginia Building Code Officials Association (VBCOA) Revise as follows: P2717.1 Protection of water supply. The water supply for dishwashers shall be protected by an air gap or integral backflow preventer. Reason: This is to clarify when Backflow Preventers are used with dishwashers. Section 2902.3.1 for Air Gaps states the standard that Air Gaps must meet and how to measure and calculate for an Air Gap. This section also says that “Air gap devices shall be incorporated in dishwashing and clothes washing appliances” but doesn’t require backflow preventers. Different sections of the code that reference the same equipment, appliances or other devices need to be consistent when requiring protection of the potable water supply. Leaving the section as it is will cause confusion for contractors and code officials when enforcing the provisions of the code. Cost Impact: The code change proposal will not increase the cost of construction.

Where installed on a wood framed floor, clothes washing machines shall be provided with a pan in accordance with Sections P2801.5.1 and P2801.5.2. Pans shall be drained by an indirect waste pipe having a minimum diameter of 3/4 inches (19 mm). Reason: Pan is required by the Plumbing code in this location but this is not in the International Residential Code. This is bringing clarity.

RP7–06/07 P2719.1

Proponent: Cecil F. Hardee, Jr., County of Fairfax, Virginia, representing Virginia Plumbing and Mechanical Inspectors Association (VPMIA) and the Virginia Building Code Officials Association (VBCOA) Revise as follows: P2719.1 Floor drains. Floor drains shall have waste outlets not less than 2 inches (51 mm) in diameter and shall be provided with a removable strainer. The floor drain shall be constructed so that the drain is capable of being cleaned. Ready access shall be provided to the drain inlet. Reason: Current text would actually permit a floor drain to mistakenly be installed beneath an appliance such as a water heater or furnace. This proposal prevents such installations from occurring. When the drain mistakenly ends up under a furnace some times the suggested fix is to cut an access panel in the bottom of the furnace housing. This is a huge problem. It is not reasonable to permit drains to be “out of sight” because they will surely be “out of mind” and the potential for sanitary problems is likely. You do not want to work on a sanitary blockage or backup through the appliance that is actually supplying the air throughout the residence. Cost Impact: The code change proposal will not increase the cost of construction. Analysis: See parallel proposal for Section 412.2 of the IPC.

RP8–06/07 P2720.1

Proponent: Lawrence Brown, CBO, National Association of Home Builders (NAHB) Revise as follows: P2720.1 Access to pump. Access shall be provided to circulation pumps in accordance with the fixture or pump manufacturer’s installation instructions. Where the manufacturer’s instructions do not specify the location and minimum size of field fabricated access openings, a 12-inch by 12-inch (304 mm by 304 mm) minimum size opening shall be installed to provide access to the circulation pump. Where pumps are located more than 2 feet (609 mm) from the access opening, an 18-inch by 18-inch (457 mm by 457 mm) minimum size opening shall be installed. A door or panel shall be permitted to close the opening. In all cases, the access opening shall be unobstructed and be of the size necessary to permit the removal and replacement of the circulation pump. Reason: The modification shown above is to correlate this same provision with the text of the IPC Section 421.5. This modification was made by the Final Action Agenda on Proposal P27-04/05. The term “pump” is added as a replacement pump may have requirements that differ from those of the whirlpool bathtub (fixture) manufacturer. Deleting the term “installation” provides more appropriate text relating to all of the instructions for the installation of appliances, and correlates with the term as used in the next sentence. Cost Impact: The code change proposal will not increase the cost of construction.

Water heaters and storage tanks shall be installed in accordance with Section M1305 and shall be located and connected to provide access for observation, maintenance, servicing and replacement. Reason: It is not the intent of the code for an obstacle to be moved or removed so a piece of equipment or appliance can be worked on or replaced. This is made clear in the section M1305.

Water heaters, other than gas-fired, having an ignition source shall be elevated such that the source of ignition is not less than 18 inches (457 mm) above the garage floor. Gas-fired appliances shall be installed in accordance with Chapter 24. Reason: This is to provide clarification to the user that fuel gas related provisions are located in Chapter 24.

Bottom fed water heaters and bottom fed tanks connected to water heaters shall have a vacuum relief valve installed. The vacuum relief valve shall comply with ANSI Z21.22. Reason: Bottom fed water heaters are installed in residences and this requirement applies. The water heater doesn’t know which occupancy in which it is installed. Currently this is not addressed in the IRC. In an effort to make this document a better stand-alone code, this requirement should be located here.

Pressure-type vacuum breakers shall conform to ASSE 1020 or CSA B64.1.2 and spill proof vacuum breakers shall comply with ASSE 1056. These devices are designed for installation under continuous pressure conditions when the critical level is installed at the required height. Pressure-type vacuum breakers shall not be installed in locations where spillage could cause damage to the structure. ICC PUBLIC HEARING ::: September 2006

IRC - RP9

Reason: Delete current requirements. The CSA B64 Standards were included in the IRC under the premise that they are same as the ASSE Standards. Upon in depth analysis, they are significantly different from the ASSE Standards. Some of the differences include different names of the devices and different abbreviations, different performance requirements, different material requirements, and different test requirements. The CSA standards are not promulgated under the ANSI process and procedures. The CSA B64 standards use metric measurements vs. English measurements. The CSA standards do not specify the order the tests should be conducted. CSA has no minimum corrosion benchmark requirements. ASSE requires materials to have a corrosion resistance equal to at least 78% copper. CSA standard covers PVB larger than 2 inches that require two check valves. ASSE does not recognize this style of PVB in ASSE 1020-2004. CSA B64.1.2-01’s check valve sealing test is a resistance to opening test, whereas ASSE 1020-2004’s is a resealing test. The CSA test does not verify the resealing of the check valve. CSA B64.1.2-01 only verifies the check valve functioning once, whereas ASSE verifies the check valve functioning five times (four times during the cycle test). During the cycle test, the CSA B64.1.2-01 does not verify that the check valve reseals. ASSE 1020-2004 has a shock (water hammer) test; CSA B64.1.2 does not. ASSE 1020-2004 includes an air passage comparative areas test; CSA B64.1.2 does not. Cost Impact: The code change proposal will not increase the cost of construction.

Flush tanks shall be equipped with an antisiphon fill valve conforming to ASSE 1002 or CSA B125. The fill valve backflow preventer shall be located at least 1 inch (25 mm) above the full opening of the overflow pipe. Reason: Delete current requirements The CSA B64 Standards were included in the IPC under the premise that they are same as the ASSE Standards. Upon in depth analysis, they are significantly different from the ASSE Standards. Some of the differences include different names of the devices and different abbreviations, different performance requirements, different material requirements, and different test requirements. The CSA standards are not promulgated under the ANSI process and procedures. The CSA B64 standards use metric measurements vs. English measurements. CSA B125 includes many products in addition to the anti-siphon fill valves. Including it as equivalent to ASSE 1002-2002 is confusing to the end user of the IRC, and inappropriate.

Add new text as follows: P2902.6 Location of back flow preventers. Access shall be provided to backflow preventers as specified by the manufacturer’s installation instructions. P2902.6.1 Outdoor enclosures for backflow prevention devices. Outdoor enclosures for backflow prevention devices shall comply with ASSE 1060. P2902.6.2 Protection of backflow preventers. Backflow preventers shall not be located in areas subject to freezing except where they can be removed by means of unions, or are protected by heat, insulation or both. P2902.6.3 Relief port piping. The termination of the piping from the relief port or air gap fitting of the backflow preventer shall discharge to an approved indirect waste receptor or to the outdoors where it will not cause damage or create a nuisance. 2. Add standard to Chapter 43: ASSE 1060–96

The flow velocity of the water distribution system shall be controlled to reduce the possibility of water hammer. A water-hammer arrestor shall be installed where quick-closing valves are used. Water-hammer arrestors shall be installed in accordance with the manufacturers’ specifications installation instructions. Waterhammer arrestors shall conform to ASSE 1010. Reason: Quick- closing valves are installed in many applications and there has not been any data showing that water hammer resulted in any damage to the plumbing system. Requiring water hammer in all cases is overly restrictive and should be removed. Cost Impact: The code change proposal will not increase the cost of construction.

2903.7, Appendix R (New) Proponent: Guy Tomberlin, Fairfax County, Virginia, representing Virginia Plumbing and Mechanical Inspectors Association (VPMIA) and the Virginia Building Code Officials Association (VBCOA) 1. Revise as follows: P2903.7 Size of water-service mains, branch mains and risers. The minimum size water service pipe shall be 3/4 inch (19 mm). The size of water service mains, branch mains and risers shall be determined according to water supply demand [gpm (L/m)], available water pressure [psi (kPa)] and friction loss caused by the water meter and developed length of pipe [feet (m)], including equivalent length of fittings. The size of each water distribution system shall be determined according to the procedure outlined in this section or by other design methods conforming to acceptable engineering practice, such as those methods in Appendix R and shall be approved by the administrative authority: code official. 1. Obtain the minimum daily static service pressure [psi (kPa)] available (as determined by the local water authority) at the water meter or other source of supply at the installation location. Adjust this minimum daily static pressure [psi (kPa)] for the following conditions: 1.1. Determine the difference in elevation between the source of supply and the highest water supply outlet. Where the highest water supply outlet is located above the source of supply, deduct 0.5 psi (3.4 kPa) for each foot (305 mm) of difference in elevation. Where the highest water supply outlet is located below the source of supply, add 0.5 psi (3.4 kPa) for each foot (305 mm) of difference in elevation. 1.2. Where a water pressure reducing valve is installed in the water distribution system, the minimum daily static water pressure available is 80 percent of the minimum daily static water pressure at the source of supply or the set pressure downstream of the pressure reducing valve, whichever is smaller. 1.3. Deduct all pressure losses caused by special equipment such as a backflow preventer, water filter or water softener. Pressure loss data for each piece of equipment shall be obtained from the manufacturer of such devices. 1.4. Deduct the pressure in excess of 8 psi (55 kPa) caused by installation of special plumbing fixtures, such as temperature controlled showers and flushometer tank water closets. Using the resulting minimum available pressure, find the corresponding pressure range in Table P2903.7. 2. The maximum developed length for water piping is the actual length of pipe between the source of supply and the most remote fixture, including either hot (through the water heater) or cold water branches multiplied by a ICC PUBLIC HEARING ::: September 2006

IRC - RP11

factor of 1.2 to compensate for pressure loss through fittings. Select the appropriate column in Table P2903.7 equal to or greater than the calculated maximum developed length. 3. To determine the size of water service pipe, meter and main distribution pipe to the building using the appropriate table, follow down the selected “maximum developed length” column to a fixture unit equal to, or greater than the total installation demand calculated by using the “combined” water supply fixture unit column of Table P2903.6. Read the water service pipe and meter sizes in the first left-hand column and the main distribution pipe to the building in the second left-hand column on the same row. 4. To determine the size of each water distribution pipe, start at the most remote outlet on each branch (either hot or cold branch) and, working back toward the main distribution pipe to the building, add up the water supply fixture unit demand passing through each segment of the distribution system using the related hot or cold column of Table P2903.6. Knowing demand, the size of each segment shall be read from the second left-hand column of the same table and a maximum developed length column selected in Steps 1 and 2, under the same or next smaller size meter row. In no case does the size of any branch or main need to be larger that the size of the main distribution pipe to the building established in Step 3. 2. Add new text as follows: Create new Appendix R to be a duplication of Appendix E of the IPC. APPENDIX R SIZING OF WATER PIPING SYSTEM Reason: The current pipe sizing method in the IRC is not usable in everyday applications as it requires piping that is too large in some cases and allows piping that is too small in others. It requires meters and service piping to be the same size and that simply is not common in many local jurisdictions. It fails to provide guidance when a meter is a different size than the service. It also fails to provide sizing criteria when the point of delivery is from a private source such as a well. Cost Impact: The code change proposal will not increase the cost of construction. Analysis: This proposal will duplicate Appendix E of the IPC in a new Appendix R in the IRC. IPC Sections 604.5 and 604.6 are referenced in Appendix E, but have no equivalent in the IRC.

Inaccessible water distribution piping under slabs shall be copper water tube minimum Type M, brass, ductile iron pressure pipe, cross-linked polyethylene/aluminum/cross-linked polyethylene (PEXAL- PEX) pressure pipe, polyethylene/aluminum/polyethylene (PE-AL-PE) pressure pipe, chlorinated polyvinyl chloride (CPVC), polybutylene (PB), cross-linked polyethylene (PEX) plastic pipe or tubing or polypropylene (PP) pipe or tubing, all to be installed with approved fittings or bends. The minimum pressure rating for plastic pipe or tubing installed under slabs shall be 100 pounds per square inch at 180°F (689 kPa at 82°C). Reason: This section is not needed. There is no need for distinction between above ground and under ground water distribution piping. This proposal achieves consistency with the IPC requirements.

Fixtures having flood level rims above the elevation of the next upstream manhole shall not discharge through the backwater valve. Backwater valves shall be provided with access. P3008.2 Construction. Backwater valves shall have noncorrosive bearings, seats and self-aligning discs, and shall be constructed to ensure a positive mechanical seal. Valve access covers shall be water tight. P3008.1 Sewage backflow. Where the flood level rims of plumbing fixtures are below the elevation of the manhole cover of the next upstream manhole in the public sewer, such fixtures shall be protected by a backwater valve installed in the building drain, branch of the building drain or horizontal branch serving such fixtures. Plumbing fixtures having flood level rims above the elevation of the manhole cover of the next upstream manhole in the public sewer shall not discharge through a backwater valve. P3008.2 Material. All bearing parts of backwater valves shall be of corrosion-resistant material. Backwater valves shall comply with ASME A112.14.1, CSA B181.1 or CSA B181.2. P3008.3 Seal.

Proponent: Guy Tomberlin, Fairfax County, Virginia, representing Virginia Plumbing and Mechanical Inspectors Association (VPMIA) and the Virginia Building Code Officials Association (VBCOA) Revise as follows: P3108.1 Horizontal wet vent permitted. Any combination of fixtures within two bathroom groups located on the same floor level are permitted to be vented by a horizontal wet vent. The wet vent shall be considered the vent for the fixtures and shall extend from the connection of the dry vent along the direction of the flow in the drain pipe to the most downstream fixture drain connection. Each fixture drain shall connect horizontally to the horizontal branch being wet vented or shall have a dry vent. Each wet-vented fixture drain shall connect independently to the horizontal wet vent. Only the fixtures within the bathroom groups shall connect to the wet-vented horizontal branch drain. Any additional fixtures shall discharge downstream of the horizontal wet vent. IRC - RP16

PUBLIC HEARING ::: September 2006

Reason: The principle of the wet vent is that all the wet vented fixtures connect to the wet vent individually. Without this proposed change, the code permits two or more fixture drains to connect together before connecting to wet vent. Similar language exists in the vertical wet vent Section P3108.4.
